Title: Platinum and platinum based alloy nanotubes as electrocatalysts for fuel cells
Inventor: YAN YUSHAN
IPC: B82B3/00
Filed: 2007-02-24
Abstract: Electrocatalyst durability has been recently recognized as one of the most important issues that have to be addressed before the commercialization of the proton exchange membrane fuel cells (PEMFCs). The present invention is directed to a new class of cathode catalysts based on supportless platinum nanotubes (PtNTs) and platinum alloy nanotubes, for example, platinum-palladium nanotubes (PtPdNTs), that have remarkable durability and high catalytic activity. Due to their unique combination of dimensions at multiple length scales, the platinum nanotubes of the present invention can provide high platinum surface area due to their nanometer-sized wall thickness, and have the potential to eliminate or alleviate most of the degradation pathways of the commercial carbon supported platinum catalyst (Pt/C) and unsupported platinum-black (PtB) as a result of their micrometer-sized length. The platinum nanotube catalysts of the present invention asymptotically approach a maximum of about twenty percent platinum surface area loss in durability test, while the commercial PtB and Pt/C catalysts lose about fifty-one percent and ninety percent of their initial surface area, respectively. Moreover, the PtNT and PtPdNT catalysts of the present invention show higher mass activity and much higher specific activity than commercial Pt/C and PtB catalysts.

Title: Process for production of high-purity diaryl carbonate
Inventor: FUKUOKA SHINSUKE
IPC: C07C69/96
Filed: 2005-10-12
Abstract: The invention aims at providing an industrially advantageous concrete process by which high-purity diaryl carbonates reduced in the content of medium-and high-boiling impurities, which are necessary for the production of high-quality and high-performance polycarbonates, can be produced stably over a long period from an alkyl aryl carbonate containing reaction mixture obtained by transesterification of a dialkyl carbonate with an aromatic monohydroxyl compound. Although many proposals were made on the production of an aromatic carbonate containing reaction mixture by reactive distillation, many studies have been made in order to find a concrete process for producing a high-purity diaryl carbonate usable as the material of high-quality and high-performance polycarbonates from the above reaction mixture stably and continuously over a long period. As a result of the studies, it has been found that the above aim can be attained by a process which comprises using three distillation columns and conducting distillation separation in a specified order. Further, it is particularly preferable that the reactive distillation column and the three distillation columns have specific structures and the three distillation columns be operated under specified distillation conditions. ® KIPO & WIPO 2009
